VENTILATING WATER CLOSET.

. Application filed May 20, 1924;. Serial No. 714,606.

To all whom it may concern:

Be it known that we, ULYSSES G. HARING, EDGAR E. SUTTER, and RALPH I'IARING, citzens of the United States of America, re-

siding in the city of lVashington, District of Columbia, have invented certain new and useful Improvements in Ventilating lVater Closets, of which the following is a speciiication.

Our invention relates to new-and useful improvements in water closets and more par ticularly to water closets that are arranged to be ventilated so that the. disagreeable 'ases and odors will be continuously drawn rom the bowl and pass oil through the vent pipe and from the instant the seat is depressed until the pressure is removed from the same. The present invention is similar in its broader aspects to the invention shown in the patentto Deike, 1,287,249 of December 3, 1918. p

In that disclosure, however, the tank and its mechanism is of special construct-ion throughout and there is-only one main supply pipe of water to the tank so that the ventilating of the bowl is also dependent on the filling of the tank. Furthermore, the seat as well as the lid enter: into the operation of the ventilation and the filling of the tank, while the pres ent application shows how the tank is filled and flushed in the regular manner and the ventilating oft-he bowl operates wholly independently of the flushing and continues to operate as long as a user remains on the seat.

The present application consists of a PTO- ferred form wherein the standard form of tank used, it only being necessary to install a small auxiliary air chamber, an auxiliary supply pipe having an air nozzle protruding into said auxiliary chamber, a valve 'con nected with the main and auxiliary supply pipes and a means for operating the last mentioned valve when pressure is applied to the seat. I

Still another object of the inventionis to utilize any one of the standard forms of tanks and supply an additional air chamber (preferred form) with an auxiliary water pipe having a spray nozzle on one end thereof, which nozzle may be regulated depending upon th amount of water pressure sup-. plied to the tank, and to further provide connecting means with a balanced seat to a valve placed between the auxiliary and main pipes for admitting water to the air nozzle, the combined instrumentalities being relatively cheap to construct and easily applied to the many tanks now in service.

Still another object of our invention is to provide means for ventilating the tank independently of the action of filling and discharging the tank, which will operate continuously, while the seat is depressed and the bowl flushed independently when desired. v

Withthese and other objects in view, our invention consists in certain new and novel structures and combination of parts as will be hereinafter more fully described and pointed out in the claim.

Referring now to the drawings showing a preferred embodiment and modified form.

draw up the gases from the bowl and through the main tank.

Fig.2is atop plan view of the same with thecover removed from the tank.

Fig. 3 1s a side elevation of a bowl and tank, part of the tank being broken away for the sake of ciearness, and a portion of thewall of the tank shown in section.

Referring now to the preferred form and more'specifically to the several views, there is shown a standard type of bowl 1 on which there a hinged seat 2, which is preferably balanced by a weight 8 on the end of a rod 4 connected to the rear end of the seat, so that the seat will normally-occupy the position shown in Fig. 3. Connected to one end of this bowl is the main flush pipe 5, which in turn leads to the bottom ofvthe tank 6, which tank may be of any standard type, and disposed centrally over the pipe valve 13 which valve is operated in the usual way by the arm 14 and ball 15.

As far as the specification has proceeded,- a standard form of tank and bowl are shown, the only exceptions being the weighted seat, and that the member 7 wit-h the valve seat and cylinder 10 are located centrally of the pipe 5 and the cylinder 10 may be slightly larger than the standard form. lso, the usual rod 16 for lifting the ball 9 from the seat is provided.

Referring now to the gist of the invention, and to Fig. 1, there is shown located in the left hand side of the tank 6, an auxiliary tank or air chamber 17 which is provided with the opening 18 at its bottom and the opening 19 at its top. the latter opening being connected with the vent pipe 20 that leads up to the roof. Also provided in the upper portion of the air chamber 17 is a further opening 21 into which projects a spray nozzle 22 located on the end of an auxiliary supply pipe 23 which pipe passes through the bottom of the tank 6. Secured to the lower end of the auxiliary pipe 23-and also connected with the main auxiliary pip 12 is avalve 24: for the admission of water to the auxiliary pipe and spray nozzle 22.

, relieved from the seat.

This means comprises a small bracket 26 through winch passes the arm 27, which at its lower end contacts with the rod 4 extendingfro-m the seat 2, a small spring 28 being shown extending between the lower end of the arm 27 and the portion of the bracket 26 for equalizing the water pressure of the valve and keeping it normally closed, while the upper end of the arm 27 is connected to the stem 29 of the valve 24 so that a downward movement of the seat permits a portion of the water from the main supply tank 12 to pass upwardly through the pipe 23 and out of the spray nozzle into the air chamber 17 to thereby create avacuum within the tank 6 and to draw the air and the odor upv through the cylinder 10 and pass them into the air chamber 17 and out through the opening 19 into the vent pipe 20.

The construction of the ordinary bowl is so well known that the small openings around the rim, in the dr wing are not shown, but it will be understood to those skilled in the art that there. is always provided a passageway around the rim so that the water besides flowing centrally into the bowl passes downwardly from the rim of the bowl to cleanse the same, and when the water nozzle 22 is in operation the air will be drawn from the bowl and from the rim of the bowl so that none of the odors will pass into the room. Of course the lid of the tank will fit snugly so that the air will be drawn from the bowl rather than from around the edges of the lid, which would be the case if the lid was not tight.

The operation from the drawings and description of the preferred form will be clearly understood and it will be seen that as soon as pressure is applied to the seat, the valve 24 will be opened so that the water from the spray nozzle into the tank 17 will create a vacuum in the tank 6 and will'continue to operate as long as the seat is de pressed to thereby draw the gases from the bowl; the entire operation being wholly independent of the flushing and filling of the tank.

From the foregoing it will be seen that the foul gases will be drawn continuously from the closet wholly independent of the filling of the tank and the flushing thereof.

Furthermore, the installation is one that may be quickly and readily accomplished and calls for but little material and little change when applied to the standard form of tanks now in service.

The tank is always full of water'similar to the regular tanks and the draft is created from the instant of the depression of the seat, rather than waitinguntil the tank is; flushed, which is the operation of some of the other ventilated closets. This is of importance as the odors and gases are never allowed to escape into the room before the draft is created by the flushing of the tank.

It will be understood that the seat will be so weighted that even though the lid is down it will not cause the valve to operate or to cause the electrical contact to be made, the lid being-provided more for the sake of looks as all of the odors will be immediately drawn out of thebowl, the moment the seat is depressed.

Many slight changes might be made withoutin any way departing from the spirit andv scope of the invention.

Having thus described our invention, what we claim as new and desire to secure by Letters Patent is The combination of a ventilated water closet comprising substantially an air tight water tank, a bowl and a pipe connecting the same, a main supply pipe for the tank, a separate air chamber in said tank and having an opening near its top, an auxiliary pipe leading from the main supply pipeto the opening in said air chamber, a valve between said auxiliary pipe and said main pipe, a depressible seat connected with said valve, a cylinder in said tank having an extension registering with the pipe from said bowl, a valvese'at in the upper part of the extension, a valve for closing the same so that normally the air may pass from said bowl and said tank, While said seat is depressed. lnto said extension through said cylinder up In testimony whereof We aflix our signainto said Water tank, and said seat when detures. 1
